Abstract: Cette invention, qui a trait à un système mémoire à disponibilité élevée, même en cas de défaillances de composants du système, concerne également des méthodes d'exploitation de ce système mémoire. Un premier et un second serveur de fichiers comportent, chacun, un journal de demande de serveur de fichiers servant à stocker des demandes entrantes de serveur de fichiers. Les deux serveurs de fichiers ont accès à un ensemble commun d'éléments de mémoire de masse. Chaque demande entrante de serveur de fichiers est copiée dans les deux serveurs; le premier serveur de fichiers traite la demande de serveur de fichiers tandis que le second serveur conserve une copie dans son journal de demandes de serveur de fichiers. Chaque serveur de fichiers fonctionne en utilisant un système de fichiers conservant un état cohérent après chaque demande de serveur de fichiers. En cas de reprise, le second serveur de fichiers peut exécuter ces demandes de serveur de fichiers dans son journal de demandes de serveur de fichiers et ce, depuis l'état cohérent le plus récent. Il n'existe pas un seul point de défaillance qui puisse interdire l'accès à un quelconque élément individuel de la mémoire de masse.

Title: Self adjusting wet brake for use with a transmission or transaxle
Inventor: JOLLIFF NORMAN E
IPC: F16D65/14
Filed: 2001-10-03
Granted: 2005-01-04
Abstract: A self adjusting wet brake positioned interior of a transaxle or transmission casing. The self adjusting brake assembly utilizes a brake pad having a cooperating ramp surface which is contacted by a brake cam for brake actuation. The cooperating ramp surface allows the brake mechanism of the current invention to automatically account for brake pad wear and the attendant decrease in brake pad thickness. As the brake pad wears and decreases in thickness, the brake cam progressively contacts the ramp surface of the brake pad to effect brake actuation. In one exemplary embodiment, the ramp surface is integral with the brake pad.

Title: Utility lighter
Inventor: TUBBY BRIAN
IPC: F23Q7/12
Filed: 2000-02-29
Granted: 2009-05-26
Abstract: The present invention relates to a utility lighter (10) including a housing (12) having a handle (14), a nozzle (18) with an outlet (64), and a fuel supply (22). An electric ignitor assembly (34) is connected to a first electrical pathway (P1) and a second electrical pathway (P2). The first electrical pathway includes a first gap (62) proximate the outlet. The second electrical pathway has operative and inoperative ocnfigurations. In the inoperative configuration, the resistance of the second electrical pathway is less than the resistance of the first electrical pathway such that electrical current generated by the electric ignitor assembly selectively travels in the second electrical pathway. In the operative configuration, the resistance of the second electrical pathway is greater than the resistance of the first electrical pathway such that the electrical current selectively travels in the first electrical pathway and jumps across the first gap to form a spark to ignite fuel from the fuel supply.

Granted: 2010-10-12
Abstract: An apparatus and method for recursive filtering of time discrete measurement data b ni(50) relating to a measurable time-varying attribute to generate an estimated magnitude for the attribute at a particular time instant n. Each measurement has an associated reliability indicator X ni(52) representing a relative reliability of the measurement. Using the individual reliability indica-tors and a time-weighted filtered reliability indicator Z n-1 for a prior time instant, a filtered reliability indicator Z n(58) for the current time instant is generated. The filtered reliability indicator for the current time instant is then used to reliability-weight a weighted average (b n) of the plurality of measurements and to reliability-weight a time-weighted estimated magnitude s n-1 for the prior time instant. The weighted values are then used to generate an estimated magnitude s n (68) of the time-varying attribute for the current time instant.

Granted: 2007-02-13
Abstract: There is provided an ignition timing control system and method and an engine control unit for an internal combustion engine, which are capable of setting optimum timing for execution of retardation of ignition timing when a vehicle on which the engines is installed is accelerated, thereby effectively reducing longitudinal vibrations of the vehicle, which might be caused by torque fluctuations, and maintaining acceleration performance. An acceleration demand-detecting module detects a demand of acceleration of the engine. A rotational speed-detecting module detects a rotational speed of the engine. A rotational variation amount-calculating module calculates a variation amount of the rotational speed of the engine, based on the detected rotational speed of the engine.      A rotational variation amount differential value-calculating module calculates a differential value of the variation amount of the rotational speed of the engine, based on the calculated variation amount of the rotational speed of the engine. A retard amount-calculating module calculates a retard amount for retarding the ignition timing. A retardation execution module executes retardation of the ignition timing by the retard amount, on condition that the demand of the acceleration is detected, that the variation amount of the rotational speed of the engine is larger than a predetermined amount, and that the differential value of the variation amount of the rotational speed of the engine is smaller than a predetermined value.
